- <dt>‘<samp>-O</samp>’</dt>
- <dd><p>The D30V can often execute two sub-instructions in parallel. When this option

- instructions can be executed in parallel.

- <dt>‘<samp>-n</samp>’</dt>
- <dd><p>When this option is used, <code>as</code> will issue a warning every
- time it adds a nop instruction.

- </dd>
- <dt>‘<samp>-N</samp>’</dt>
- <dd><p>When this option is used, <code>as</code> will issue a warning if it
- needs to insert a nop after a 32-bit multiply before a load or 16-bit
- multiply instruction.
